3 Claims.

The present invention relates to machines for ruling paper sheets, and particularly to that type in which the ruling pens are in the form of rotatable disks.

The object of the present invention is to provide such a pen and a mounting therefor which is extremely simple and inexpensive, yet which will be adjustable for different types of ruling, and which will be efficient in use.

In the accompanying drawings:

Figure 1 is a plan view showing a series of pens in position on the supporting shaft, and showing also the means provided for longitudinally adjusting the pen members on the shaft.

5- Figure 2 is a sectional view on line 22 of Figure 1.

Figure 3 is a sectional view on the line 33 of Figure 1.

Figure 4 is a sectional view on the line 44 of Figure 1.

Figure 5 is an enlarged View of a portion of the ruling apparatus, the pens being shown in section.

Figure 6 is a sectional view of one of the pens.

Figure '7 is a perspective view of one of the pens. Figure 8 is a view of a portion of the pen bearing shaft showing another method of associating the pens.

The type of ruling machine with which the invention is intended for use is so generally known that it is deemed to be unnecessary to show and describe it in detail. A pen supporting shaft 1 is provided, which shaft is journaled in supporting members 2, and suitably driven, as by gears 3, 4, 5 and 6 journaled in the same supporting members 2, and parallel to the shaft 1 is an inking roller '7, which may consist of bearing spindles 8, a metal core 9, and a rubber or other yielding covering 10. Ihe inking roller 7 is so spaced from the shaft 1 as to contact the pens 11 which are borne by shaft 1.

The pens 11 are formed by stamping or pressing them from sheet metal, such as brass. Each pen 11 is formed in the shape of a disk having a circular aperture 110, in the center, a circular disk portion 12 having the ruling edge 13, and an offset cylind lcal flange 14 encircling the aperture 11a. The internal diameter of the flange of the pen is very slightly smaller than the shaft 1, so 0 that upon placing the pen upon the shaft 1, as shown in Figures 1, 5 and 8, the cylindrical flange portion 14 will frictionally but firmly engage the surface of the shaft 1 and prevent movement of the pen thereon, either circumferentially or longitudinally. The edges 13 of the pens 11 come into contact with the roller '7 and are inked thereby as the shaft 1 and pens 11 revolve.

In order to longitudinally adjust the pens on the shaft 1, the following mechanism is provided. Upon each of the supporting members 2 is mounted a pin 15. A rod 16 is adapted to be detachably mounted upon these pins 15 by means of the aperture 1? and slot 18 that receives the same. Mounted upon the rod 16 in a manner permitting it to be moved longitudinally of the rod 16 is a bracket 19 having a bearing hub 20 and a forked end 21 in which is journaled a wheel 22. In order to change the position of a pen upon the shaft 1, the rod 16 bearing the bracket 19 is mounted upon the pins 15. The shaft is then set in rotation. The bracket 19 is then moved about the rod 16 until the wheel 22 comes into contact with one of the pens 11. By pressing the bracket 19 and consequently the wheel 22, in the direction in which it is desired to move the pen, the pen 11 may be easily moved upon the shaft 1 to the required position. Due to the frictional engagement between the flange portions 14 of the pens and the shaft 1, the pens will not of themselves move upon the shaft 1.

As shown in Figure 8, by placing pens upon the shaft 1 in such a manner that the flange portions 1 1 of adjacent pens are on the opposite outer sides of the pens, the ruling edges 13 of the pens may be brought into very close proximity to each other and consequently very close parallel lines may be ruled.

The advantages of the invention are obvious. The pens are inexpensive and simple to manufacture. They may be easily and quickly installed and adjusted for use upon a rotary pen type ruling machine. They are adapted to rule narrowly spaced parallel lines. They are strong and durable and are efiicient in use. Moreover by using sheets of different gauge, ruling pens with various widths of edges can be produced that Will rule lines of corresponding widths.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim is:

1. In a ruling machine, the combination with a pen carrying shaft, of a series of ruling disks mounted on the shaft and having integral portions frictionally engaging the shaft so that the disks normally rotate with the shaft but may be slipped axially therealong, and means mounted to move along the shaft for longitudinally adjusting the ruling disks upon the shaft.

2. In a ruling machine, the combination with a pen carrying shaft, of a ruling disk that is mounted on the shaft and having an offset flange, the internal diameter of said flange being normally slightly less than the diameter of the shaft, said flange being thereby caused to frictionally bind upon the shaft and normally hold the disk against movement on the shaft While permitand normally hold the disk against movement on the shaft While permitting the disk to be shifted by sufficient force to different places upon the shaft.
